Sir Alex Ferguson has called Jurgen Klopp "one of the most gifted managers in world football" ahead of the German's 1,000th game.
The Liverpool manager, 55, will reach the landmark when his team welcome Graham Potter's Chelsea to Anfield on Saturday afternoon. His managerial career has lasted for nearly 22 years after long spells with Mainz, Borussia Dortmund and now the Reds.
Klopp has won 12 trophies as a manager - including the Premier League title and Champions League - and legendary Manchester United boss Ferguson has paid tribute to his contemporary by releasing a statement through the League Managers Association.
